Caddyman over at androidforums has posted up a new Android 2.1 leak for the Droid Eris. There's a huge list of bugfixes, and from the looks of it the odd connectivity issues Eris users were seeing with the previous leaks should have been addressed, as well as the pesky bugs with the latest Google Voice app. For those of you running one of the previous leaks, this is something you'll want to look at for sure!
Warning - This is leaked beta testing software, and wasn't meant for general use. Flashing it will wipe your phone, and take away root if you have it. As always, use your best judgment and flash at your own risk!
Links, changelog, and further instructions can be found HERE. Thanks, kbaker!
